Which AC/heat system and why?

I don't see why that would not work fine. My belt goes around three pulleys, one of which is adjustable (the manual idler pulley). Yours will also go around three pulleys also, one of which is adjustable (the PS pulley). I'd be fine with that.
Thanks. Thats probably why I can't find anyone to comment because most likely no one has had any problems with it.
